Firefox didn't seem to like me moving my home folder. Even though the firefox profile says its located in thew new location, a bunch of addons and core firefox components are giving errors every time I start it up now.
edit: false alarm - I re-dragged Firefox to the applications from the download DMG, and it reset the profile and addons.
Down to 36 gigs now. That's probably plenty small for a 60gig SSD.
MR.com can be such a helpful place when you don't spend your time trolling.
